A boolean value indicating whether the lobby supports standard messages or not. An application can request this property from the lobby to determine if it supports standard messages. If the lobby does not respond to this message or if it responds with FALSE, then the application should assume that it does not support standard lobby messages and not send any further messages. If the lobby returns TRUE, then the application should freely send standard messages to the lobby and query for further properties of the lobby.
For this property, the dwPropertyData field of the DPLMSG_GETPROPERTYRESPONSE structure will contain the following:
BOOL fMessagesSupported;
